Phlox plant named &#39;Cleopatra&#39;

ABSTRACT

A new and distinct cultivar of  Phlox  plant named ‘Cleopatra’, characterized by its tall upright plant habit; dark-green colored leaves; freely flowering habit; long flowering period; red purple-colored semi-double flowers; and good cut flower and garden performance.

BOTANICAL DESIGNATION

Phlox paniculata

CULTIVAR DENOMINATION

‘CLEOPATRA’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phloxplant, botanically known as Phlox paniculata and hereinafter referred toby the cultivar name ‘Cleopatra’.

The new Phlox plant originated from a cross-pollination of two unnamedproprietary selections of Phlox paniculata, not patented, in 2010. Thenew Phlox was discovered and selected by the Inventor as a singleflowering plant from within the progeny of the stated cross-pollinationgrown in a controlled greenhouse environment in Hillegom, TheNetherlands in July, 2012.

Asexual reproduction of the new Phlox plant by vegetative cuttings in acontrolled greenhouse environment in Hillegom, The Netherlands sinceFebruary, 2013, has shown that the unique features of this new Phloxplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phlox have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Cleopatra’. These characteristics incombination distinguish ‘Cleopatra’ as a new and distinct Phlox plant:

1. Tall upright plant habit.

2. Dark-green colored leaves.

3. Freely flowering habit.

4. Long flowering period.

5. Red purple-colored semi-double flowers.

6. Good cut flower and garden performance.

Plants of the new Phlox and the parent selections differ primarily inflower form as plants of the parent selections have single-type flowers.

Plants of the new Phlox can also be compared to plants of Phloxpaniculata ‘Windsor’, not patented. In side-by-side comparisonsconducted in Hillegom, The Netherlands, plants of the new Phlox and‘Windsor’ differed primarily in flower color and form as plants of‘Windsor’ had apricot orange-colored single-type flowers. In addition,plants of the new Phlox were slightly taller than plants of ‘Windsor’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH The accompanying colored photographillustrates the overall appearance of the new Phlox plant showing thecolors as true as it is reasonably possible to obtain in coloredreproductions of this type.

Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Phlox plant. The photograph is a side perspective viewof a typical flowering plant of ‘Cleopatra’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in an outdoor nurseryin Hillegom, The Netherlands and under commercial practices typical ofcommercial Phlox production. During the production of the plants, daytemperatures ranged from 16° C. to 32° C. and night temperatures rangedfrom 6° C. to 18° C. Plants were six months old when the photograph anddescription were taken. In the following description, color referencesare made to The Royal Horticultural Society Colour Chart, 2007 Edition,except where general terms of ordinary dictionary significance are used.
